I eventually made suspend work with 2.6.19.1
my config is ubuntu edgy
vanilla kernel from kernel.org, with all mactel patches.
The problem is still with the piix chip which seems to be suspended 2 times
(or maybe too early?).
I have enabled the CONFIG_PM_DEBUG, which writes the hash of the last module
suspended (see driver/power/trace.c for more info how it works)
My (temporary) solution is too disable the suspend for the ata hosts:

I cant imagine there is no better way to do that..
Any Idea?
